La resistance de l'air is nothing else than a bad rehash of a very good novel by James Hadley Chase: Like a hole in the head. When I saw the names behind the script, I wasn't surprised at all since they also made another bad rehash of a very good film with Les Cowboys (rehash of John Ford's The Searchers).
The film is totally empty and flat. It's also anti-climatic in so many ways. This being sold as a crime film, you expect at least that it would deliver the goods. Nothing happens. If you expect some muscles and some sparks flying, you'll be disappointed.
A reviewer pointed out how close it was to Colt 45, another french crime film. I can see why but Colt 45 is a much better film than La resistance de l'air. From what I heard Colt 45 was slaughtered in the editing room but even in its actual form it beats Fred Grivoi's picture on every level.
My advice: Forget this film. Read Chase's Like a hole in the head and watch Fabrice du Weltz's Colt 45 instead.
